TensorFlow 2.0 Computer Vision Cookbook

By: Jesús Martínez

Overview of this book

Computer vision is a scientific field that enables machines to identify and process digital images and videos. This book focuses on independent recipes to help you perform various computer vision tasks using TensorFlow. The book begins by taking you through the basics of deep learning for computer vision, along with covering TensorFlow 2.x’s key features, such as the Keras and tf.data.Dataset APIs. You’ll then learn about the ins and outs of common computer vision tasks, such as image classification, transfer learning, image enhancing and styling, and object detection. The book also covers autoencoders in domains such as inverse image search indexes and image denoising, while offering insights into various architectures used in the recipes, such as convolutional neural networks (CNNs), region-based CNNs (R-CNNs), VGGNet, and You Only Look Once (YOLO). Moving on, you’ll discover tips and tricks to solve any problems faced while building various computer vision applications. Finally, you’ll delve into more advanced topics such as Generative Adversarial Networks (GANs), video processing, and AutoML, concluding with a section focused on techniques to help you boost the performance of your networks. By the end of this TensorFlow book, you’ll be able to confidently tackle a wide range of computer vision problems using TensorFlow 2.x.

Predicting age and gender with AutoKeras

In this recipe, we'll study a practical application of AutoML that can be used as a template to create prototypes, MVPs, or just to tackle real-world applications with the help of AutoML.

More concretely, we'll create an age and gender classification program with a twist: the architecture of both the gender and age classifiers will be the responsibility of AutoKeras. We'll be in charge of getting and shaping the data, as well as creating the framework to test the solution on our own images.

I hope you're ready because we are about to begin!

Getting ready

We need a couple of external libraries, such as OpenCV, scikit-learn, and imutils. All these dependencies can be installed at once, as follows:

$> pip install opencv-contrib-python scikit-learn imutils

On the data side, we'll use the Adience dataset, which contains 26,580 images of 2,284 subjects, along with their gender and age. To download the...
